Description

차량용 출력증강 및 연료절감장치{an output reinforcement and fuel retrenchment device for cars}An output reinforcement and fuel retrenchment device for cars}

본 발명은 차량용 출력증강 및 연료절감장치에 관한 것이다.The present invention relates to a vehicle power augmentation and fuel saving device.

보다 상세하게는 연료와 혼합되는 혼합공기를 엔진내부로 공급시킴에 있어서, 흡입되는 공기 중에 섞여있는 먼지, 이물질, 습기, 유해가스 등등을 비롯한 각종 오염물질 등을 2차에 걸쳐 완벽하게 여과시켜 공급시킴으로서 출력증강과 매연감소, 그리고 이로 인한 연료절감효과 등이 탁월하도록 한 것이다.More specifically, in supplying the mixed air mixed with fuel into the engine, various contaminants such as dust, foreign matter, moisture, harmful gases, etc. mixed in the inhaled air are completely filtered through the second stage. By increasing power output, reducing soot, and reducing fuel consumption, it is excellent.

주지된 바와 같이 종래에도 여러 종류의 연료절감기가 있었으나 이들을 차량에 장착하여 주행하다 보면 초기에는 그런대로 효과가 있기는 하나 시간이 지나면지날수록 그 효과가 미미하여 별 다른 효과를 기대할 수 없었던 것이다.As is well known, there were several types of fuel savers in the past, but when they were mounted in a vehicle, they were initially effective as they were, but the effects were insignificant as time passed.

다시 말하면, 종래의 연료 절감기는 엔진으로 공급되는 공기를 단순히 엔진열에 의해 예열 공급시킬 수 있도록 구성된 것으로서, 연료와의 혼합기 구성시 예열 공급된 공기에 의해 폭발능력이 다소 증가된다고는 볼 수 있고, 이는 곧 예열된 공기와 연료가 혼합기를 구성함으로서 엔진이 부드럽고 조용해지는 경향은 있다 할 수 있으나, 연료절감효과나 매연감소효과를 비롯하여 출력증강효과는 그다지 높지 못한 등의 폐단이 따랐던 것이다.In other words, the conventional fuel saver is configured to simply preheat the air supplied to the engine by the heat of the engine, and it can be seen that the explosive capacity is slightly increased by the preheated air when the mixer with the fuel is configured. In other words, the preheated air and fuel tend to make the engine softer and quieter, but the fuel saving effect, the soot reduction effect, and the power increase effect are not so high.

따라서 본 발명은 전술한 종래의 제반문제점을 감안하여 발명한 것으로서, 특히, 차량엔진의 흡기 메니홀드에 연결 설치하여 엔진이 가동되어 외부 공기를 강제 흡입할 때 외부공기를 2차에 걸쳐 여과시킴으로서 공기 중에 함유된 먼지, 유해가스, 이물질 등등의 각종 유해물질을 매우 신속 간편하게 여과시켜 맑고 깨끗한 공기만을 엔진내부로 공급시킬 수 있게 하고, 이에 따라 연료와 혼합 작용하여 혼합기를 구성할 때 완전연소를 유도하여 매연감소, 출력증강 및 연료절감효과가 극대화되게 하는 차량용 출력증강 및 연료절감장치를 제공하려는 데 발명의 목적이 있는 것이다.Therefore, the present invention has been invented in view of the above-mentioned conventional problems, and in particular, by connecting to an intake manifold of a vehicle engine, the engine is operated to filter the outside air for two times when the outside air is forced to inhale the outside air Various harmful substances such as dust, harmful gas, and foreign substances in the air can be filtered very quickly and easily, so that only clean and clean air can be supplied into the engine. It is an object of the present invention to provide a power output and fuel saving device for a vehicle that maximizes soot reduction, power increase and fuel saving effect.

이하, 본 발명의 작용을 보다 상세하게 설명한다.Hereinafter, the operation of the present invention in more detail.

본 발명은 엔진룸 내부에 설치 고정하되, 여과공기 배출관(24)일단에 설치고정된 호스연결구(24b)와 결합된 여과공기 공급호스(6)의 끝단은 엔진의 흡기 매니홀더에 연결 설치한다. 이때 흡기 매니홀더에 상기 여과공기 공급호스(6)를 연결설치할 때 차량에 기 장착된 흡기 호스도 동시에 연결 설치할 수 있도록 Y형 호스 연결구를 이용하여도 된다.The present invention is installed and fixed inside the engine room, the end of the filter air supply hose 6 coupled with the hose connector 24b fixed to the filter air discharge pipe 24 is installed in connection to the intake manifold of the engine.

이와 같이 본 발명의 출력증강 및 연료절감장치를 차량에 장착한 상태에서 시동을 걸면 외부의 공기가 여과장치(5)의 흡입구멍(52)을 통하여 강제 흡입되며, 흡입된 공기는 여과장치(5)내부에 내장된 활성탄소에 의해 1차적으로 유해가스, 먼지, 이물질, 습기 등등과 같은 이물질이 여과된 상태에서 공급호스(52)와 외부공기 흡입관(22)의 공기흡입구멍(21)을 거처 필터(3)의 유입구멍(33)으로 유입되고, 상기 필터(3)로 유입된 공기는 필터(3) 내부에 내장된 활성탄소(32)와 필터케이스를 구성하는 주름진 여과지(34)를 통과하면서 또 한번 여과된 후 필터(3)와 본체(1) 사이로 나온 뒤 뚜껑(2)에 형성된 여과공기 배출구멍(24a)과 여과공기 배출관(24), 그리고 호스연결구(24b)와 여과공기 공급호스(6)를 통하여 엔진의 흡기메니홀드로 공급되게 되는 것이다.In this way, when the engine is started with the output boosting and fuel saving device of the present invention mounted on the vehicle, external air is forced to be sucked through the suction hole 52 of the filtering device 5, and the sucked air is filtered. By passing through the air suction hole 21 of the supply hose 52 and the external air intake pipe 22 in a state where foreign substances such as harmful gases, dust, foreign matters, moisture, etc. are primarily filtered by the activated carbon contained therein. The air introduced into the inlet hole 33 of the filter 3 and the air introduced into the filter 3 pass through the activated carbon 32 embedded in the filter 3 and the pleated filter paper 34 constituting the filter case. And once again filtered and then passed between the filter (3) and the main body (1), and then the filter air outlet hole (24a) and the filter air discharge pipe (24) formed in the lid (2), the hose connector (24b) and the filter air supply hose Through (6) it is supplied to the intake manifold of the engine.

위와 같이 2차에 걸쳐 여과된 맑고 깨끗한 공기가 엔진내부로 유입되어 연료와 함께 혼합기를 형성하게 됨에 따라 자연적으로 완전연소가 이루어질 수 있게 되는 것이며, 더불어 불완전연소가 없어 매연이 발생될 염려가 현저히 줄고, 완전연소로 인하여 파워(power) 즉, 출력이 크게 증강되는 등의 효과가 따르게 된다는 것이다.As above, clean and clean air filtered through the secondary flows into the engine to form a mixer together with the fuel, so that natural combustion can be completed completely, and there is no fear of generating soot because there is no incomplete combustion. In other words, due to complete combustion, power, that is, power is greatly increased.

다시 말하면, 여과장치(5)에 의해 수분, 먼지, 유해가스 등의 유해물질이 1차 여과된 후, 다시 필터(3)에 의해 2차 여과되어 흡입된 공기 중에 함유된 모든 불순물과 습기 등을 제거해주기 때문에 완전연소를 크게 신장시키게 되고, 이에 따라 연료소모율을 극소화시켜 줄 수 있게 되어 연료절감효과를 극대화시킬 수 있음은 물론, 완전연소로 인하여 매연이 극소화되어 공해 예방효과 또한 극대화시킬 수 있게 된다는 것이다.In other words, after the first filtering of the harmful substances such as moisture, dust, harmful gases, etc. by the filtering device (5), the second filter is again filtered by the filter (3) to remove all impurities and moisture contained in the sucked air. Because it removes, it greatly increases the complete combustion, thereby minimizing the fuel consumption rate, thereby maximizing the fuel saving effect, and minimizing the smoke due to the complete combustion, thereby maximizing the pollution prevention effect. will be.

이상 설명한 바와 같이 본 발명은 활성탄소를 이용하여 공기를 2단계로 여과시킬 수 있도록 함에 따라 맑고 깨끗하며 순수한 공기만이 엔진내부로 유입되게 되고, 이에 따라 완전연소가 이루어질 수 있게 되어 연료절감효과 및 배기가스와 매연감소효과가 탁월하며, 더불어 출력이 크게 증강됨과 동시에 엔진의 수명연장에도 기여할 수 있는 매우 유용한 발명인 것이다.As described above, the present invention allows the air to be filtered in two stages using activated carbon, so that only clean, clean and pure air is introduced into the engine, and thus, complete combustion can be achieved, thereby reducing fuel consumption and Exhaust gas and soot reduction effect is excellent, and it is a very useful invention that can greatly increase the power and contribute to the life of the engine.
